github-status-resource

A Concourse resource to interact with the GitHub Status type.

Configuration

• repository - the owner and repository name, slash delimited (e.g. dpb587/github-status-resource)
• access_token - GitHub API access token (minimum scope of repo:status)
• branch - the branch currently being monitored (default: master)
• context - a label to differentiate this status from the status of other systems (default: default)
• endpoint - GitHub API endpoint (default: https://api.github.com)
• skip_ssl_verification - Disable certificate validation for GitHub API calls (default: false)

Behavior

check

Triggers when the status of the branch for the configured context has been updated.

in

Lookup the state of a status.

• /commit - the commit reference of the status
• /description - a short description of the status
• /state - the state of the status
• /target_url - the target URL associated with the status
• /updated_at - when the status was last updated

out

Update the status of a commit. Optionally include a description and target URL which will be referenced from GitHub.

Parameters:

• commit - specific commit sha affiliated with the status. Value must be either: path to an input git directory whose detached HEAD will be used; or path to an input file whose contents is the sha
• state - the state of the status. Must be one of pending, success, error, or failure
• description - a short description of the status
• description_path - path to an input file whose data is the value of description
• target_url - the target URL to associate with the status (default: concourse build link)

Example

A typical use case is to update the status of a commit as it traverses your pipeline. The following example marks the commit as pending before unit tests start. Once unit tests finish, the status is updated to either success or failure depending on how the task completes.

---
jobs:
  - name: "unit-tests"
    plan:
      - get: "repo"
        trigger: true
      - put: "repo-status"                               # +
        params: { state: "pending", commit: "repo" }     # +
      - task: "unit-tests"
        file: "repo/ci/unit-tests/task.yml"
        on_failure:
          - put: "repo-status"                           # +
            params: { state: "failure", commit: "repo" } # +
      - put: "repo-status"                               # +
        params: { state: "success", commit: "repo" }     # +
resources:
  - name: "repo"
    type: "git"
    source:
      uri: {{repo_uri}}
      branch: {{repo_branch}}
  - name: "repo-status"                                  # +
    type: "github-status"                                # +
    source:                                              # +
      repository: {{repo_github_path}}                   # +
      access_token: {{repo_github_token}}                # +

When testing pull requests, use the PR ref as the branch. For example, if testing PR #12345 to your repository, your resource might look like...

name: "pr-status"
type: "github-status"
source:
  repository: {{repo_github_path}}
  access_token: {{repo_github_token}}
  branch: "pull/12345/head"           # +

For another pipeline example, see ci/pipelines/main.yml which operates against this repository.

Installation

This resource is not included with the standard Concourse release. Use one of the following methods to make this resource available to your pipelines.

Deployment-wide

To install on all Concourse workers, update your deployment manifest properties to include a new groundcrew.resource_types entry...

properties:
  groundcrew:
    additional_resource_types:
      - image: "docker:///dpb587/github-status-resource#master" # +
        type: "github-status"                                   # +

Pipeline-specific

To use on a single pipeline, update your pipeline to include a new resource_types entry...

resource_types:
  - name: "github-status"                         # +
    type: "docker-image"                          # +
    source:                                       # +
      repository: "dpb587/github-status-resource" # +
      tag: "master"                               # +
